Abstract
The invention proposes a high-voltage direct current cut-off device, comprising: in series, a cut-off device and a current limiter; an accumulation line in parallel with the current limiter, an oscillating circuit, in parallel with the cut-off apparatus, comprising an oscillation control switch and having an inductance wherein the accumulation line includes at least two accumulation capacitors, and in that the oscillation line extends from a branch connection point of the accumulation line situated between the two accumulation capacitors, determining a secondary segment of the accumulation line connected to the main conduction line between the current limiter and the main cut-off apparatus so as to form part of the oscillating circuit.
